| Abstract: | The mix design of the anti-abrasion concrete used in the anti-abrasion parts of the dam is studied on the basis of the engineering practice in this paper.The properties of the anti-abrasion concrete were also tested,including mechanical deformation,anti-abrasion performance,crack resistance,permeability resistance and frost resistance.Besides,a contrastive test on the crack resistance of the anti-abrasion concrete is performed by incorporating anti-abrasion agent,poly-carboxylic acid water reducer and Napht... |
